Good game, the only flaw is that the randomness sometimes make the boss fight really easy, and sometimes its impossible. 2 times i got there and he summoned a minion ON me, and i lost my hero. Another time there were two blocks on the top but they were soooo far from each other that there was no way to go on them and jump on the boss, i had to take a hit and then jump on him, but the 4th time the blocks were on a perfect position so i just smashed the boss really easy
Cosmic monolith: get all dark defense you can get (i got 60% on matt, 30% on nat and 40% on lance) and cast Barrier at the start of the fight. This should reduce the damage to around 5k
Then keep using Lance's Syphon and the monolith will stand still
To kill the tank you throw a grenade at it, an then shot the bunny that is on top of it
I got to lvl ~35 almost just with the colt.45 and the assistant
On the first level i put some mushrooms on the cross path, 1 slow,2 instant death, 1 life stealer, 1 area poison and other random... getting these to lvl 5 is a really nice idea
I've beaten the game with this strategy:
Set AutoSend on
Leave the arrow in any line, sending spearman if dificulty < 50% and swordman if dificulty > 50%
The game gets very boring when we learn this strategy =P
